The Keysight 34902A is a 16-channel high-speed multiplexer module that expands measurement capacity within modular data acquisition systems. This single-pole, 16-throw multiplexer enables rapid sequential channel switching with minimal signal degradation, making it ideal for high-throughput data acquisition workflows. Low insertion loss preserves signal integrity across all channels, while low thermal EMF supports sensitive measurement applications. The module integrates directly into compatible Keysight mainframes via standard slot insertion and accepts programmatic control for automated channel selection and multiplexer operation.
